- Why does rain have to be wet?
- Why does snow fall?
- What is with swimsuit, bathing suit and birthday suit? Clearly these are all informal occasions so why the suit?* (I propose: swim and bathing threads and birthday robe)
- Why do trees have to be bare during the coldest time of the year?
*In other countries where English is spoken well, they use the word costume instead of suit. Costume makes me feel as though I need to dress like Spiderman before I dive into the pool.
